Advanced ECC (Standard) Memory Technology
This section details the features and DIMM installation requirements for advanced
ECC memory.
Features
Advanced ECC memory has the following advantages:
• The ProLiant ML500 series Generation 2 servers support up to 32 GB of system
memory. Each memory board supports up to 16 GB of system memory using
2-GB DIMMs.
• Advanced ECC memory detects both single-bit and multi-bit errors, and corrects
single-bit errors. It can also detect and correct 4-bit errors that occur within a
single DRAM chip on a DIMM.
DIMM Installation Requirements
Observe the following DIMM configuration requirements when installing DIMMs:
• Use only industry-standard PC1600 registered DDR SDRAM DIMMs in
256-MB, 512-MB, 1-GB, and 2-GB capacities.
• Install DIMMs in pairs, one bank at a time.
• Be sure that both DIMMs in a bank are the same capacity.
• Be sure that bank A is populated.
IMPORTANT: HP recommends that you use only HP DIMMs. Third-party DIMMs may have
additional installation requirements. For information about third-party DIMM installation
requirements, refer to the Advanced Memory Protection white paper on the website:

IMPORTANT: You must power down the server before installing additional DIMMs.
